Letters Patent No. 90.7 89, dated June 1, 1869.

IMPROVEMENT IN MACHINE FOR WIRING BLIND-SLATS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern county of Essex, and State of New Jersey,have in-' vented certain Improvements in Machines for Wiring Blind-Lathsand Rods; and declare the following, when taken in connection with the dawings that accompany this specification, to be a full andexactdescription of the same.

The nature of our improvement consists in a provision for obviatingefiectually, the difiicnlty heretofore found to be a great disadvantageto the machine, namely, that of a second staple getting under the driverbefore the first has been driven to its proper depth; also preventingthe occasional annoyance of a staple sticking fast in the machine, fromvariation in the thickness of the wire used for staples.

The machine is shown completely in Figure 1, in the drawings, in whichthe only new feature is the independent stop, or cut-oil of} the supplyof wires to the driver, shown by A, in its position, in combination withthe other parts of the machine, and is seen by itself in Figure 2.

-The slide for the staples B is inclined, that the staples may be movedto the driver 0 by their gravity.

The holder, or slide, standing at a right angle to the face-of themachine, and the cut-off having its fulcrum, a, outhe face, it of courserests its extreme on the slide, and holds back the coming wire stapleuntil it is lifted.

The spring b gives the needed pressure to the point. of the cut-oil uponthe slide, and keeps it to its place.

The end e, of the lever cut-off A, is so placed that the operatinghandle D cannot touch it until it has moved the driver down to withinahout the thickness of the wire above the stopping-point of a staple,when driven to the required depth; hence no movement of the cut-offtakes place until the staple is so far out of the way that the nextsucceeding staple cannot inter- .fere with the former, nor clog themachine.

As when the point of the cnt-ofi is lifted, the staples slide until oneis in contact with the face ofthe driver 0, and the least upwardmotion-of the handle, when down to its lowest point, allows the spring1/ to press the point of the cut-off either on the top of the secondstaple, or on the slide between the first and second staple, effectuallyand inevitably holding back all but the one that is against the driver,leaving that free, no staple can get under the driver when lifted, untilthe preceding one has been driven to its place; for the cut-off nuthaving been touched, has not allowed another staple to pass, and itcannot be touched until the first is driven to its place.

We are aware of the lever-oontrivances by which a cut-ofi' is operated,having a continuous, or a reciprocating motion, dependent on connectionby levers, none of which have as yet been so constructed as topractically obviate the difiiculties, so that the workman could have hiswork go on smoothly, free from petty annoyances; we therefore disclaimall such leverconnections;

What we do claim as new, and desire. to secure by Letters Patent, is

In a machine for wiring blind-slats, the independent cut-0d A, providedwith the spring I), or its equivalent, when constructed and operatedsubstantially in the manner and for the purpose specified and shown.
